POST-DRIVER.

SPECIFICATION forming part of Letters Patent No. 304,953, datedSeptember 9, 1884. 4

Applicationitiled May 19, 1884. (No model.) Y i To all whom, it mayconcern:

Be it known that I, WHARTON B. PHILBERT, a citizen of the United States,and a resident of Linneus, in the county of Linn and State of Missouri,have invented certain new and useful Improvements in Portable Fence-PostDrivers 5 -and l do hereby declare that the following is afull, clear,and exact description ofthe in vention, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, which form a part of thisspecification, and in which- Figure l is a perspective view of myimproved fencepost driver. Fig. 2 is avertical section of the same. Fig.3 is a horizontal section; and Figs. et and 5 are perspective de tailviews of the sledge and its bearings and of the springs drawing it back.

Similar letters of reference indicate corresponding parts in all thegures.

My invent-ion has relation to fencepost drivers; and it consists in theimproved construetion and combination of parts of the same, as

hereinafter more fully described and claimed.

, In the accompanying drawings, the letter A indicates arectangularupright frame, mounted upon a wheeled or sliding platform, B, andforming rectangular ways, C, in its corners, in which the inner cornersof the corner-posts D of a rectangular sliding frame, E, slide. Theupper ends of the corner-posts of the upright frame are provided withpulleys F, over Which pass ropes or chains G, attached at their lowerends to the lower end of the sliding frame at its four corners, andattached at their upper ends to the ends of a windlass, H, journaledtransversely in bearings I, formed upon the upper1 edges of two of thesides of the upright frame, and having a circumferential series ofperforations, J, at one end, which are engaged by the outerdownwardly-bent end of a hook, K, pivotcd upon the side of the uprightframe. One side of the sliding frame has two vertical posts, L L, whichform L-shaped recesses, M, at their middle upon their inner sides, theupper horizontal portions of which recesses open in the outwardly-facingsides ofthe posts, while the lower ends of their vertical portions formbearings for the trunnionsvN of a roller,

O, in which the inner'end of the handle of the' sledge P is secured, thesledge projecting out at right angles to the roller. A treadle, Q, ispivoted at one end upon the lower end of the sliding frame at the foot0f the vertical posts, and slides with its outer portion in aguide-bail, It, upon the side of the frame, and a rope or chain, S, issecured to near the outer end of the treadle, passes around the roller,and is secured to the same, and another rope or chain, T, is secured tothe other end of the roller, passes a few turns around the same, and issecured to the upper inwardly-bent end of a spring, U, consisting `of adoubled rod having its lower ends slightly divergent, and secured in thelower cross-bar of the side of the sliding frame opposing tothe slcdge.The upper portion of this spring bears against the outer side of atransverse spring-bar, V, secured transversely upon the side of thesliding frame opposite to the sledge, serving to add springiness to thedoubled spring.

It will now be seen that the platform, with the driver-frames, may berolled to the posthole, the post inserted, when, by depressing thetreadle, the Sledge may be brought down upon the top of .the post,whenthe springs will again raise the Sledge, and the sliding frame maybe lowered by means of the windlass,and be held in"its adjusted positionby means of the hook engaging the perforations in the end of thewindlass as the post is driven into the ground.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United Statesl. The combination ol" an uprightrectangular frame provided with pulleys at its upper corners and mountedupon wheels or runners, a rectangular frame sliding upon the uprightframe, asledgc pivotedupon the sliding frame and having means foroperating it, a windlass j ournaled in the upper end of the uprightframe and having means for stopping it, and ropes secured to thewindlass passing over the pulleys at the upper corners of therectangular frame, and secured to the lower end of theV sliding frame atits corners, as and for the purpose shown and set forth.
